MANIFOLDING COPYING-BOOK.

Specification of Letters Patent.

Patented Nov. 30, 1909.

To all whom it may concern:

Be it known that we, CHARLES G. C. \VHYTE, a citizen of the Commonwealthof Australia, residing at Pile street, Marrickville, Sydney, in theState of New South Vales, Commonwealth of Australia, accountant, andARTHUR RAU, a citizen of the Commonwealth of Australia, residing at No.53 Terry street, St. Peters, Sydney aforesaid, professional shorthandwriter, have invented certain new and useful Improvements in andRelating to Manifold Copying-Books; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

By means of this invention provision is made to further increase thenumber of reproduced copies of written matter in books hithertoserviceable either for duplicating or triplicating purposes, in whichthe well known method is adopted of using, in combination with theleaves, an interleaved transfer or copying sheet, whose withdrawal willallow of the combined sheets being detached, while the copying medium isavailable for further use. Such books have been in use for recordingcounter sales, orders out, accounts, correspondence, and the like.

By our improved devices hereinafter described with the aid of doublefaced transfer paper, used either singly or folded, in association witha separate packet of transparent sheets, the number of copies may beincreased from two to three, or from two to five, as may be required.This is accomplished by using conjointly the covers of the book, andattaching to their inner sur faces two sets or packets of leaves, soplaced in juxtaposition that they will, when the book is closed, be incontact with each other, one set being composed of transparent sheetsonly, and the other of opaque sheets only, or of opaque sheets (singleor folded) in combination with single transparent sheets.

Referring to the drawings which form part of this specification: Figure1 represents an ordinary duplicating book. Fig. 2 shows covers of a bookmade suitable for the application of this invention, with index inposition on the back cover. Fig. 3 represents a packet of transparentsheets suitable for attachment to a cover as in Fig. 2. Fig. 4represents a packet of opaque folded sheets as at present in use, fittedwith combined clips and hinges for attachment to a cover as in Fig. 2.Fig. 5 represents a packet of combined transparent and single opaquesheets, prepared for attachment to a cover as in Fig. 2, serviceablewith a folded trans for sheet to produce additional. copies. Fig. 6shows the covers as in Fig. 2 combined with packets of leaves as inFigs. 3 and 1-. Fig. 7 shows the covers as in Fig. 2 combined withpackets of leaves as in Figs. .3 and 5. Fig. 8 is an edge view of aclosed book, showing packets overlying. Fig. 9 shows the hinged packetfolded over the transparent packet, to give access to the index. Fig. 10is a detail of a combined packet clip and eyelet, also serviceable forattachment to the cover. Fig. 11 is a detail of staple for attachment tocovers to receive eyelet, also serviceable for attachment to the packet.Fig. 12 shows the method of detaching transparent and folding leavescombined.

The back and front book covers, A and B, are joined by the flexiblepiece C, which is made of a width to correspond to the combinedthickness of the packets D and E, which need not necessarily be of thesame thickness because the materials of the two are diiferent. Thepacket D is composed of ordinary paper sheets, or of such interleavedwith transparent sheets or tracing paper interspersed in any desiredorder and serviceable either as single or folded sheets as may bearranged, to accord with the use of a single piece of double facedcopying paper F, which may be bound up with the packet D, or left loose,or to accord with a folded piece of double faced copying paper F F. Thepacket E is made up wholly of sheets of transparent paper, or tracingpaper, lightly secured at the edges E so as to be easily separated. Itis intended that these packets shall be secured to their respectivecovers, so that when the book is opened for use each set will occupy aposition distinct from the other, thus either or both sets may the stockof leaves is being exhausted, the thickness of the stub will remain thesame. Duplicate books with leaves so constructed are at present providedwith devices to retain the stubs in position until the completeexhaustion of the packet, but no provision is made in them foroverturning the packet to enable the cover to which it is attached to beexposed to View on the inside, therefore this invention is devised toallow of this being done, because it is essential that the salesmansindex G shall be removed from cover B, Fig. l, and transferred to theinside of cover A, Fig. 2, the slit parts A formed in the binding usedfor the purpose. This index, which is used by the salesman for recordingthe amount of each sale, is used as frequently as the packet D whichoverlies it, and in whose leaves the duplicate, triplicate, ormultiplicate records are to be made. Ordinarily such leaves are bound inpackets with wire fastenings piercing the stub portion D and are rigidlyheld againstthe surface of the cover by clips and backing pieces.

To render the packet removable a new form of combined staple and eyeletH and combined hook or lug and staple H (Figs. 10 and 11) are provided,to be used in association with the packet D and the cover A. Bothdevices act as clips or binders by piercing the material and clenchingthe ends over the surfaces. Three of the combined clips and eyelets Hare shown attached to the stubs D in Figs. t and 7, and a similar numberof combined clips and staples H are fixed to the cover A, Figs. 2, 6,and 7. The eyelet-s H preferably lie at the surface level of the stub D,as indicated in Figs. 8 and 9. Each hook H is passed through the corresponding eye H, as shown in Fig. 9, but may be readily separatedtherefrom at will. In said figures the transfer sheet is shown in dottedlines.

In Fig. 9 the packet D is shown overlying the packet of transparentsheets E which rests on the cover B, thus allowing free access to theindex G, the staples H standing at a suflicient height to allow of afree movement of eyelets H, and wholly avoiding any movement of thecover A, which is allowed to lie fiat for writing purposes. The flexiblepart C readily accommodates itself to the changed position of the packetD, which, when thus positioned, has its perforated line D coincidingapproximately with the edges E of packet E. This packet is held inposition against the cover B by the bottom tongues E inserted in theslits B formed in the cover B, which prevents the packet from beingdisplaced. As an additional precaution against the separation of theleaves forming the packet E, they are held at the corners in housings Bformed of stiffened covering material having sufficient spring to engagewith the corners of the packet as its thickness diminishes. Theindividual leaves of packet E may be separated therefrom successivelyand transferred to the packet- D. A single leaf is thus used with thelatter when a single sheet of transfer paper F is available. Two suchleaves are thus transferred when a folded sheet F F of transfer paper isused.

The packet of transparent leaves remaining in its position upon cover B,may be folded over, as in Fig. 8, without fear of disarrangement; and itis intended that while the stock of opaque, or combined opaque andtransparent, leaves is removed, what remains of the packet E shall fallinto the space created by the removal of the leaves of packet D, takinga position against the stub I), and allowing the covers of the book tobe closed in a proper manner, the flexible piece C accommodating itselfto this arrangement.

It is to be understood that while the combined clip and eyelet H and thecombined clip and staple H are shown attached to the stub D and thecover A respectively, the order of attachment may be reversed, in whichcase the configuration of the respective devices would be as showndotted in Figs. 10 and 11, the object being to place the eyelet in avertical position when attached to the cover A, and the staple in ahorizontal position when attached to the stub D Either of these devices,when attached to the cover, will not need renewal, but as each stub isremoved the fresh packet would have its own attachments to engage withthe permanent parts on the cover.

In Figs. i and 6, the double-sided transfer sheet F is shown secured tothe stub D to be overlaid upon the lower portion of the folded opaquesheet D. The transparent sheet taken from packet E would be laidthereon, and be kept in position by the upper portion of the foldedopaque sheet D, upon which the original writing would be made, as atpresent. The writing, of course, would be visible through thetransparent sheet. here the folded double sided transfer sheet is used,and the transparent sheets are interleaved in the same position as forthe single transfer sheet, a further set of copies would be produced.

By the combination of two separate sets or packets of leaves in the samebook, provision is made either for producing a series of duplicatecopies and a series of triplicate copies, or aseries of triplicatecopies only, or, they may be taken alternately in dupli cate andtriplicate, but the discontinuance of the taking of triplicate copieswould not result in the loss of the transparent sheets, which are stillheld in reserve for use when required.

In Fig. 12 a triplication of writing is shown effected with atransparent sheet removed from the packet E, the loose sheet and thefolding sheet being removed simultaneously, the single transfer sheet Ffalling naturally into position upon the packet E.
